Sam’s pre op consultation was both informative and reassuring and his manner was engaging and charming. He and his team are amazing - after a pain free total knee replacement, I was walking unaided within a week. Genius Thank you Roger Berry

I was operated on by Mr Sam Rajaratnam for a complex total knee replacement. From the first consultation I had with Sam I was impressed by how unhurried he was and how he carefully explained what he proposed to do. I came away from that consultation relaxed and confident that I was in safe hands. But there is so much more. Sam has created a team of himself, an anaesthetist Dr Barry Phillips and a nurse Christine Howis who are a formidable trio. They act as one and take the time to explain things slowly and in detail and explain fully the pros and cons of any options available. The pain relief was 100% effective and I can confirm that from the time I entered the hospital until I left on day four I was never in any pain. The treatment was exemplary. Needless to say any questions I asked of the team was answered promptly and fully explained in an unhurried and friendly manner. I also feel that Sam's practice managers/secreterial staff Venetia and Daisy were always friendly and efficient and responded to any query promptly and in a friendly unhurried manner. So all in all a dream team who I can strongly recommend. And there is yet more! Sam has teams of physiotherapists in different areas associated with his practice who call on you at your home both pre and post op and arrange for the delivery of an ice machine and setting it up for you. What more can I say? So here I am about six weeks post op walking with one crutch which I don't really need and having booked Sam and his team to do the other knee in the not too distant future!

I cannot recommend Sam and his team highly enough. I have had full replacement of both my knees at the Horder Centre this year (Feb and Sept). To be fully mobile and back driving again just three weeks post op is incredible. I can honestly say my experience has been nothing less than exceptional. I felt completely reassured from my initial consultation and throughout the surgical process. I am thrilled by my results and I can't wait to start living my life to the full again pain-free. Thank you so much Sam.

I have had knee replacement in both legs under the care of Mr Sam Rajaratnam at The Horder Centre in Crowborough East Sussex, both procedures were successful. The first was a year ago and I was driving my car after three weeks and the second was three weeks ago and I was given the ok to drive after two weeks by Mr Rajaratnam, the criteria being able to do an emergency stop without any problems. After both operations there was very good pain control and no complications. I highly recommend Mr Rajaratnam who is very experienced and knowledgeable. After both operations he visited me on the following day for a chat and answered any questions I had and I always felt confident under his care.

Sam and his team were brilliant. Knee replacement revision. Quick recovery, minimal pain. Sam delivered as promised, clear guidance and post surgery support. Dr Barry Phillips controlled pain relief, minimising trauma, aiding recovery. Daily visits and checks from Sam and Barry during hospital, great bedside manner. My thanks to Christine (consultant nurse) for follow up appointments. Special thanks to Aaron (physio from Cheyn Voss physio), for expertise and enabling me to get those extra degrees of flexibility.

Sam was amazing through my whole operation process. I felt very heard when I had concerns or questions and when the actual operation came along he made me feel relaxed. My sister used Sam to operate on her knee 10 years ago and hasn’t had any problems since! I’m hoping the same will be for me, I’m sure it will as Sam is constantly developing new technologies to make the process as seamless as possible. The way I was able to walk without crutches after one week and barely taking pain killers was incredible, other people who I followed on social media were taking much longer to get to that point. So amazed with the recovery so far and highly recommend using Sam! Also a special mention to Dr Barry Phillips his anaesthetist is also amazing, I felt immediately comfortable and reassured during the process! Even when receiving the injection to put me to sleep he made me feel so at ease.

Couldn't recommend Sam Rajaratnam and his team more highly. Of course knee replacement is a daunting operation but from the first meeting with Sam I felt confident and completely reassured because he took time to listen and explain. Sam and his team - Dr Barry Phillips his anaesthetist, Dr Ari Johar general practice, clinical nurse Christine Howis, Venetia and Daisy his practice managers, physio Mark Williamson who visits home were easy to discuss treatment and extremely supportive. They visit constantly during the three day stay. The whole experience was surprisingly managed with a low pain threshold. The team work in unison and nothing is too much trouble. I was so impressed. Sam Rajaratnam and his colleagues along with the highly trained nursing staff, and the superb facilities of the Cleveland Clinic, are unique in offering excellent surgery and care. Think of the experience similar to a Formula One pit stop. The 'Team' descend on you and you come out the other end a new person ready to live an improved pain free life!

I have recently received a knee replacement carried out by the amazing surgeon, Mr Sam Rajaratnam and his team. I received the best care and attention from my initial contact and throughout the procedure and aftercare, not only from Sam but the whole team including his anaesthetist Dr Barry Phillips (who made the whole process more comfortable than I could have imagined was possible, by using a combination of techniques and medications), the nursing staff at the Cleveland Hospital and Sam’s senior nurse Christine and of course Cheyne Voss, the physiotherapist, who has got me well and truly on the road to recovery. I cannot recommend this team highly enough to anyone facing the need for this surgery, requiring to get back to full function in the shortest time frame and yet having undergone a virtually pain free experience.

I had a full knee replacement on 11/03/24 at Cleveland Clinic under the excellent care of Sam Rajaratnam. the procedure went smoothly and i had no pain during or after recovery. Sam was honest & explained everything to me at our first consultation, & I immediately liked him & trusted him. Sam has performed over 7,000 knee replacement operations and he has pioneered many details and thereby changed a painful, difficult procedure into a tolerable, less painful one. Sam has a wonderful team working with him, including Barry (anaesthetist), Christine, (Nurse consultant) Vinny (practice manager) & others. I hope that i do not have to have a knee replacement on my right knee, but if i do i would not look at any other doctor or team other than Sam & his team.
